Analyze and improve business profitability with financial insights
ROIC measures how efficiently a business turns debt and equity into after-tax operating profit — NOPAT divided by invested capital. Learn the formula, why it beats ROI and ROE, the WACC benchmark that separates value creators from value destroyers, and the five calculation mistakes owners make most.
Throughput accounting reduces business decisions to three numbers — throughput, investment, and operating expense — and argues that only fixing the single binding constraint, not cutting costs everywhere, increases how much money a business actually makes.
Economic Value Added (EVA) = NOPAT − (WACC × invested capital) — the profit left after every source of capital, debt and equity alike, is paid its going rate. A worked example, how to estimate NOPAT and WACC, why EVA avoids ROI's percentage bias, and how small business owners can use it for capital decisions.
Pet waste removal services gross $20–$45 per visit at ~50% gross and ~20% net margins, with top operators reporting $2M+ in annual revenue. This bookkeeping guide covers the metrics that actually decide profitability — revenue per route-hour, deferred revenue on prepaid subscriptions, and separating residential cash flow from invoiced commercial contracts.
GMROI measures gross profit generated per dollar of average inventory cost; a GMROI above 3.0 is generally strong, below 1.0 means inventory is destroying margin dollars, and typical category ranges run from 1.2 in grocery to 6.5+ in electronics.
LLM inference is a variable cost of delivering your product, not software overhead — ICONIQ's 2026 data puts AI product gross margins at a 52% industry average, well below the 70-80% typical of traditional SaaS.
Machine shops that track only labor and materials miss the two costs that decide whether a job is profitable — machine overhead and work in process — so aggregate revenue looks healthy while a third of jobs quietly lose money.
A $150 mobile detail costs $15-$20 in chemicals plus fuel, equipment wear, and unbilled quote time; tracking cost-per-job, the 72.5-cent 2026 IRS mileage rate, Section 179 equipment write-offs, and profit-per-drive-hour reveals whether a detailing business is actually as profitable as its revenue suggests.
Under ASC 606, cash rebates, slotting fees, and co-op advertising payments to a customer almost always reduce revenue rather than count as a marketing expense, unless the payment buys a distinct good or service at fair value.
Prepaid training packages are a liability, not income — how fitness studios should use deferred revenue accounting, classify instructors under the FLSA economic-reality test, and track the KPIs, like the 70–75% class utilization benchmark, that separate profitable studios from struggling ones.
Rental e-bikes and scooters are fixed assets, not inventory — and useful life ranges from under two months for early shared scooters to 2–3+ years for reinforced fleet hardware. How micromobility operators should structure a chart of accounts that separates batteries, theft, and field-ops labor, calculate contribution per vehicle per day, book damage deposits as liabilities, and find breakeven on blended seasonal utilization rather than peak-week numbers.
Demand charges can account for 30–70% of a commercial electricity bill and add roughly $9,000 to a single month when six DC fast chargers peak simultaneously — yet most operators blend them into one utilities account. How to book charging revenue against per-kWh COGS, track the Section 30C credit that now sunsets June 30, 2026, and model realistic payback periods for Level 2 ($4,500–$12,000/port) and DC fast chargers ($90,000–$200,000/port).
